          Fun tool, for edc, would have liked to see a little more edge on this model, but I guess I'll just have to upgrade in the future.

          Hey Nate, I do make the Talon version which is mechanically Identical to the version you purchased, but adds a Hardened stainless steel double-edged razor sharp reinforced tip, the edges are about 1' down each side. If you'd like to return your knife to trade-up or receive a refund I will cover shipping for either option.
